Precautions for handling the LCD module
Appendix A Handling the LCD Module
3. If the panel’s surface gets dirty, wipe it with cotton or a soft cloth. If it is still dirty, try breathing on the surface to create a light condensate and wipe it again
5. Glass is used in the panel, so be careful not to drop it or let it strike a hard object, which could cause breakage or cracks
7. Do not expose the module to direct sunlight or strong ultraviolet rays for long periods
